SUBSTITUTING COMPLEMENTS

Complements ?

This paper revises the interdependence between flexible technology and product innovation in the context of a monopolistic firm. Previous literature argued that flexible machinery reduces the cost of incremental innovation. To take interactions beyond the fixed cost into account, we introduce a 2-period optimization model where technology, innovation and price are chosen first, then stochastic ...

Substituting Touch for Vision

We are currently exploring relaying navigational information (e.g., obstacles, terrain, depth) to a visually impaired person using a tactile glove we have developed. The glove consists of a collection of vibrating motors. The collective patterns of motor activity are used for conveying the navigational information which is mapped from an artificial perception system derived from a wearable came...

Substituting Quantum Entanglement for Communication

We show that quantum entanglement can be used as a substitute for communication when the goal is to compute a function whose input data is distributed among remote parties. Specifically, we show that, for a particular function among three parties (each of which possesses part of the function’s input), a prior quantum entanglement enables one of them to learn the value of the function with only ...

Perceptual issues in substituting texture for geometry

An important goal in interactive computer graphics is to allow the user to interact dynamically with three-dimensional objects. The computing resources required to represent, transmit and display a three dimensional object depends on the number of polygons used to represent it. Many geometric simplification algorithms have been developed to represent the geometry with as few polygons as possibl...
